7B is a fan designation and wouldn't be on a real script.
The episode has a title, so why isn't it here.
It was shot in 2012 so why is the script dated 2013.
All real scripts are watermarked with the name of the person they're for.

This is clearly fake, however I remember how lame it sounded when someone posted dialog suggesting Captain Jack would travel clinging to the outside of the Tardis and it'd be revealed he travelled through time with a wristband like it was a space hopper. Nobody believed that, it sounded so bad...then Utopia arrived

I do wonder if the end of episode 8 (or in fact the whole episode) will lead into the anniversary special in some way though?
